EMB ROIDERING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 325,499, dated September 1, 1885.

Application filed March 27, 1885. (No model.)

To all whom it may concern:

Be it known that I, FRANKLIN H. CHILTON, a citizen of the United States, and a resident of New Rochelle, in the county of Westchester and State ofNew York, haveinvented certain new and useful Improvements in Embroidering Attachments for Sewing Machines, of which the following is a specification.

The invention relates to an improvement in embroidering attachments for sewing-machines; and it consistsin an attachment of the construction hereinafter described and particularly pointed out in the claims. 7 Figure 1 of the drawings is a side elevation i 5 of an embroidering attachment embodying the elements of the invention, the operatinglever being shown in a depressed position. Fig. 2 is a top view of the foot of the attachment showing the position of the thread-car; 2c rier and embroidering-thread when the operating-lever is depressed. Fig. 3 is a similar view of same, illustrating the position of the thread-carrier and embroidering-thread when the operating-lever is elevated. Fig. dis a 2 5 detached perspective view of the switch for giving the thread-carrier a lateral movement, and Fig. 5 is an enlarged view of the stitch formed by the attachment sought to be pro tected hereby.

In the accompanying drawings, A denotes the supporting bracket or frame of the attachment, having, at its lower side, the inclined plate B, the front portion of which projects in front of the bracket and forms a presserfoot, 0. The bracket A is adapted to be secured to the presser-foot bar of a sewing'machine in the customary manner.

Upon the plate B, and in line with its greatest length, is arranged a reciprocating plate, 0 F, passing through slots in the front and rear ends of the bracket A. The plate F is provided upon one side with the arm J, which projects through a slot, K, cut in the side wall of the bracket, and is engaged by the 5 notch L, formed in the lower end of the vibrating arm M, which is pivoted, at N, upon the bracket, and by means of which, when in motion, the plate F is given a longitudinal reciprocating movement and with it the thread-carrier hereinafter described.

Upon the outer face of the vibratingarm M is secured the pin 0, which projects through the camslot Q, formed in the actuating-lever R, whereby motion is communicated from the lever to the arm. 5 5

Upon the under side of the plate F is arranged the thread-carrier X, the rear end of which is pivoted to the adjacent end of the plate F, while its forward end projects over the resser-foot and is provided with eyes Z and an elevated point, a. The thread-carrier X. being pivoted to the plate F, has a longitudinal sliding movement therewith, and also a lateral vibratory motion when actuated by the switch I) and lever B, as hereinafter speci- 6 5 fied. The formation of the switch I) is more clearly illustrated in Fig.4, in which it will be seen that the device consists of a circular plate having a slot, 6, in its front depending edges through which passes the thread-carrier X, the central portion of the plate F being removed, forming an elongated slot, S, so as to permit the engagement of the switch and carrier. The switch b is applied to the end of the lip d by means of a screw, d, upon which, when actuated, it has a pivotal movement. The lip d is one end of an angular piece of sheet metal which projects laterally over the slot S, the other end of said angular piece of metal being secured in contact with the inner face of the bracket A, as indicated at w.

The switch I) is provided with a lateral extension or arm, f, which projects through the rear portion of the slot K into suitable relation to be engaged alternately by the projecting ends 9 of the lever B when the latter is in motion. The movement of the lever It 0perates to vibrate the arm f, which gives the switch a partial rotary movement upon the screw d, whereby the ihreadcarrier X is 0 given a lateral vibratory movement without interfering with its longitudinal reciprocation. The space between the projecting points 9 on the lever B is to permit a definite length of the longitudinal movement of the thread-car- 5 rier before either of said points strikes the armf of the switch I) and imparts the vibratory movement to said carrier, the purpose being to give the carrier a direct forward and backward movement before causing it to loop the thread on the stationary thread-detainer T, hereinafterdescribed. The lever B will be connected with the needlebar of the sewing machine, so as to communicate motion there from in the customary manner.

The central portion of the front edge of the foot (Jis removed, forming an opening, V, in which the embroi dering stitches areformed and sewed to the goodsby theusual sewing-needle, and upon one side of which is firmly secured the hook-shaped threaddetainer T, curving from a point at one side of the vertical path of the sewing-needle over the opening V and extending directly rearward beyond the point where the sewing-needle enters the fabric being embroidered.

The embroidering-thread is passed from .a suitable spool downward through the eye m, thence through the reareye Z of the threadcarrier and along the side of the carrier to the front eye Z, through which it is passed, and then carried below the presser-foot.

In the operation of the invention the downward throw of the lever B, caused by the depression of the needlebar, will move the vibrating lever M, plate F, and th read-carrier X to their rear position, as indicated in Fig. 2. At the same time the lever B operates through the switch I) to move the said carrier on its pivot to the right-hand side of the longitudinal line of center of the presser-foot, looking at the front of the needle-opening V, as shown in Fig. 2. Upon the lever B being moved upward by the elevation of the needle-bar, the plate F and carrier X are moved forward by means of the vibrating lever M, and during their forward movement the rear point g of the lever B will strike the arm f of the switch b, moving it forward, and thereby turning the switch upon its pivot, whereby the carrier X is moved to the opposite side of the path of the sewing-needle, crossing the end of the detainer T, which at this point catches the embroidering-th read, retainingit while the carrier moves to the opposite side of the needle-opening V and to the front of the vertical plane of the needle. Upon the subsequent depression of the needle-bar and lever B the thread'carrier will move directly rearward, and then across and in rear of the path of the sewing-needle in position to again move the thread forward, at the same time the sewing'needle enters the fabric beneath the presser-foot in the loop of the embroidering-thread formed on the point of the detainer, and the usual feed of the fabric moves the thread from off the detainer, permitting it to be sewed in position.

The lever B, switch 1;, bar M, and threadcarrier X are shown and described in my application for Letters Patent for improvements in embroidering attachments for sewing-machines filed January 5, 1885, and bearing Serial No. 152,054, and are not consequently indepently claimed herein.

The thread-detainer T may be a bent piece of wire soldered to the foot 0, or it may be retained thereon in a sleeve, 00, which will permit it to be turned from over the opening V, as shown in dotted 1ines,-for the purpose of affording an unobstructed inspection of the stitches being formed.

What 'I claim as my invention, and desire to secure by Letters Patent, is

1. In an embroidering attachment for sewing-machines, the plate B, foot 0, and supporting-bracket, in combination with the longitudinally-reciprocating and laterally-vibrating thread-carrier applied on said plate and perforated at its front end to receive the embroideringthread, the stationary thread-detainer located on the resser-foot and projecting rearward over the needle-opening in same at one side of thepat-h of the sewing-needle, and mechanism, substantially as described, for communicating motion from the needle-bar of the sewing-machine to the said carrier, substantially as set forth.

2. In an embroidering attachment for sewing-machines, the combination, with a supporting-bracket and presser-foot, of a threadcarrier pivoted at its rear to a reciprocating plate, a stationary hook-shaped thread-detainer projecting rearward over the needleopening in the presser-foot and at one side of the path of the sewing-needle, and mechanism, substantially as described, for commnnirating a longitudinally-reciprocating motion to said plate and carrier, and a laterally-vibratory movement, to the carrier from the needle-bar of the sewing-machine, substantially as set forth.

3. In an embroidering attachment for sewingmachines, the combination, with a supporting-bracket and presser-foot, of a longitudinally-reciprocating and laterally-vibrating thread-carrier, the thread-detainer T, secured in a sleeve, 01;, on the presser-foot at one side of the path of the sewing-needle, and
